Abstract
A lubricant includes carbon particles in a carrier. The carbon particles may be nearly spherical, individually have maximum and minimum diameters that differ by no more than ten nanometers, and the maximum diameters of the carbon particles are less than one micrometer. The lubricant may be manufactured by preparing the carbon particles by ultrasound-assisted polymerization of resorcinol and formaldehyde in an aqueous system followed by a heat treatment in an inert or non-oxidizing atmosphere and dispersion of the carbon particles in the liquid hydrocarbon carrier to form the lubricant. Optionally, inorganic metals, alloys, or oxides are coated on the surface of the carbon particles via an additional thermolysis step.
